The cricket frog's range in New York has contracted significantly over the past century. Dozens of known populations have been extirpated, including all of those on Long Island and Staten Island, as well as several on protected State Parks in southeastern New York. Only a quarter of those that remain (11) are deemed to be of fair or better viability, and only five of those appear to be healthy. All but one of these occurs on private land, where ongoing and persistent threats continue to imperil this species.
Populations from at least nine known sites have become extirpated since the late 1980s, although most were already quite small (<10 calling males). In addition, many of the extant populations have declined dramatically since the early to mid 1990s. Two new sites were discovered in Dutchess County in 1993, extending the range east of the Hudson River (Dickinson 1993). It is unclear whether this represented a range expansion or increased survey effort.
Historically this species was found on Long Island, Staten Island, and in the lower Hudson River valley. By 1930, Long Island populations had disappeared, as had those on Staten Island by the mid 1970s (Gibbs et al. 2007). Cricket frogs have become extirpated from no fewer than 20 historically occupied sites since about 1900, representing a significant range contraction within the state.
